Nomenclature adjustments and new syntaxa of the arctic, alpine and oro-Mediterranean vegetation

Proposte sintassonomiche e nomenclaturali per la vegetazione della Tundra alpina. Il capitolo riguardante l'alta quota appenninica è il più corposo e propone il nuovo syntaxon Leontopodio-Elynion a livello di alleanza. La grande novità sta nel fatto che questa alleanza è da considerarsi anfi-Adriatica e unsice Appennino e balcani, differenziandosi dall'alleanza già definita da altri per le Alpi. i Pirenei e i Carpazi.During preparation of the European checklist of vegetation units (EuroVegChecklist), it became clear that some earlier described syntaxa need to be typified in order to stabilize nomenclature and some new syntaxa need to be described. Here we propose nomenclature adjustments and formal description of four new alliances for the Arctic, alpine and oro-Mediterranean vegetation of Europe, Greenland and Anatolia. First, we typify the class Juncetea trifidi. Second, we describe four new alliances, such as the Puccinellion nuttallianae (Low-Arctic salt steppes of Greenland; class Saxifrago tricuspidatae-Calamagrostietea purpurascentis), Dryado octopetalae- Caricion arctisibiricae (Arctic tundra vegetation of north-eastern European Russia; class Carici rupestris-Kobresietea bellardii), Leontopodio nivalis-Elynion myosuroidis (southern European alpine tundra vegetation; class Carici rupestris-Kobresietea bellardii) and Lagotido uralensis-Caricion ensifoliae (alpine tundra vegetation of the Southern Ural Mountains; class Juncetea trifidi). Two new associations are described within the first two of these alliances. Finally, we present an interpretation of the alliance Muscario-Scillion nivalis

Geoecological Characteristics and Comprehensive Assessment of the Effectiveness of Urban Improvement Management in a Large Siberian City

Introduction. The issues of creating, preserving and improving the quality of green areas are relevant not only for the municipality — the city of Barnaul, but also for each urban settlement of the Russian Federation, village and settlement.Methodology. To identify numerous shortcomings in the management, a statistical analysis of the main indicators of the development of the improvement sector, the main opinions of «experts», was carried out. In order to find ways out to ensure the comfort of living for each resident of the city, a theoretical generalization is used.Results. The main geoecological characteristics of the municipality — the city of Barnaul – are described. It reflects not only the achievements of local governments in this area, but also highlights the main problem-the lack of a unified concept of landscaping. To predict the development of the city and the formation of a unified approach to landscaping, the main measures are proposed that will allow creating an up-to-date, and most importantly, allowing each resident to comfortably exist, a model for managing the field of landscaping.Analysis and discussion. The forecast estimate for the municipality — the city of Barnaul from the proposed measures for rational use of natural resources is given.Conclusions. The application of these results is not only possible, but it is also necessary to take into account the local self-government bodies when managing the geoecological processes of each city of the Russian Federation in order to achieve an optimal standard of living for the population

Application of Membrane Filtration to Prevent Microbial Contamination of Lysimeter Water

Ultrafiltration is suggested for the elimination of artifacts evolved from the biochemical transformation of water-soluble organic substances in lysimeter collectors. A membrane filter installed between the vessel of the lysimeter and its collector provides the separation of microbial cells from water-soluble organic substances immediately at the infiltrate accumulation

Civic education of the technical university students in foreign language classes

© 2015, Canadian Center of Science and Education. All rights reserved. The article is devoted to the theory and techniques of the young people civic education. It also deals with the problems of students’ civic consciousness and civic qualities formation. The purpose of the research was to study and diagnose civic consciousness of Technical University Students, to ground theoretically and test experimentally pedagogical conditions of students’ civic consciousness formation in foreign language classes. The results of the definition and specification of the notion of “civic education” are also introduced in the article. Forms and methods of efficient work in classroom and extra-curricular work with students while studying a foreign language are revealed and experimentally checked. The efficiency of testing, dialogue around, role-playing games, press conferences, debates in civic consciousness formation is approved

Problems and prospects of development of ecological tourism in Ireland

The paper presents the research on the development of ecological tourism in Ireland. The basic directions and problems of development of ecotourism. Income from ecotourism in the country was analyzed in the article, as well as the model for the attraction of tourists to Irelan

The infrastructure of public catering in the context of tourist city space development

To assess the impact of environmental factors on the activities of catering enterprises of the Belgorod region and the quality of customer service, the authors proposed a method using STEP-analysis and SWOT-analysis. The analysis of environmental factors was carried out on the basis of the expert evaluation results conducted in two stage

Fabrication of microscale medical devices by two-photon polymerization with multiple foci via a spatial light modulator

Two-photon polymerization is an appealing technique for producing microscale devices due to its flexibility in producing structures with a wide range of geometries as well as its compatibility with materials suitable for biomedical applications. The greatest limiting factor in widespread use of two-photon polymerization is the slow fabrication times associated with line-by-line, high-resolution structuring. In this study, a recently developed technology was used to produce microstructures by two-photon polymerization with multiple foci, which significantly reduces the production time. Computer generated hologram pattern technology was used to generate multiple laser beams in controlled positions from a single laser. These multiple beams were then used to simultaneously produce multiple microstructures by two-photon polymerization. Arrays of micro-Venus structures, tissue engineering scaffolds, and microneedle arrays were produced by multifocus two-photon polymerization. To our knowledge, this work is the first demonstration of multifocus two-photon polymerization technology for production of a functional medical device. Multibeam fabrication has the potential to greatly improve the efficiency of two-photon polymerization production of microscale devices such as tissue engineering scaffolds and microneedle arrays
